Abstract:
A field experiment was conducted during kharif season of 2016 and 2017, to evaluate the effect of different doses of phosphorus and liquid bio-fertilizers on maize at District Seed Farm (AB Block), Kalyani, Bidhan Chandra Krishi Viswavidyalaya, Nadia, West Bengal on silty clay loam soil having pH 7.25, medium in available N (250.20 kg/ha), high in available P (26.20 kg/ha) and medium in available K (280.12 kg/ha). The experiment was laid down in RBD design with three replication having twelve treatments viz. T1: Control (Recommended N and K), T2: PSB I, T3: PSB II, T4: NPK consortia, T5: 60 kg P2O5/ha, T6: 30 kg P2O5/ha + PSB I, T7: 60 kg P2O5/ha + PSB I, T8: 30 kg P2O5/ha + PSB II, T9: 60 kg P2O5/ha + PSB II, T10: 30 kg P2O5/ha + NPK consortia, T11: 60 kg P2O5/ha + NPK consortia and T12: 90 kg P2O5/ha. In maize field, highest grain yield (12,297 and 11,980 kg/ha), stover yield (14,232 and 13,678 kg/ha), net return (Rs. 1, 10173/- and 1, 38,099/-) and B: C ratio (3.94 and 4.06) were obtained in treatment T11 receiving 60 kg P2O5/ha + NPK consortia which was followed by T10 treatment (30 kg P2O5 + NPK consortia) during both the years, respectively. The experimental results revealed that, 60 kg/ha P2O5 + NPK consortia was best treatment combination for maize in new alluvial zone of W. B which not only increased maize productivity, net income, supplementing balance nutrition to the maize but also improves the soil health by synthesize/assimilate atmospheric nitrogen, solubilizes phosphate, potash, unavailable micro-nutrient into available form and prevent environmental pollution.
